Stupid and mythical. First off one of the most exaggerated things fan use in boxing is physical strength, we don't know any objective measures of their strength , he's not an infighter, and nothing about Froch showed me he was any more than those 2 were at their primes. Froch would not stop either of them IMO. Only HUGE punchers stopped Hearns, and prime Leonard was never closed to being stop by any of the large punchers he faced, we can even go back to Olympics with HUGE Ko artist Aldama who KO'd granite chin McCallum. Froch could beat them at 168, but I think they were smart and skilled and had enough pop to beat him. Kessler was near old and was schooling Froch who tried to fight off of the back foot and looked very silly. Joshua probably is the "strongest" guy at HW. It didn't save him from getting brutally KO'd by a fat journeyman. Haney lifts tons of weights, it didn't stop him from getting put on ***** street by Linares.
